Are you asking how you know the start date of a thread? Look at the first post in the thread. For example, you started this thread today at 7:14:23. That date and time are under the thread title on the first post of the thread. Or do you mean you want to do an automated search by start date?

I guess if those are the only ways to find out the first post date then I would like to just make a suggestion that it would be a plus to be able to see the start date of a post without opening the thread or searching . Thank you I will suggest it to the moderator.
